I just love tearing apart the lower dashboard.
What I was doing was I replaced the EFAS SPDT button with a momentary SPST button which powers the coil of a DPDT relay. One side switches the VSS signal for EFAS, the other side opens the circuit on my clutch switch. Having a clutch switch activated can prevent Auto-Stop either from my EFAS or from normal driving conditions, so it's good that this one button now takes care of both of those. I suppose I could have gotten a TPDT relay so that I could wire in the temperature resistor too, but I didn't want to go that far.
And here it is all put back together.
